2. Description of Related Art

General residential interior design uses hanging cabinet facilities for home storage items, and the space below the cabinets usually designed to place a workbench. Personal book cabinet and the reading desktop below the bookcase, or the wide cabinets in the kitchen and the cooking bench below the cabinets need under cabinet lighting with proper size fitting in with the corresponding cabinet. In other words, the lighting below the cabinet is an important part of indoor lighting. As the cost of the LED (light-emitting diode) decreases, along with the development of lighting technology and the advantage of saving energy for the LED, the LED has gradually been the main light source of the cabinet lighting for residential design.

Most of the commercially available LED cabinet lights are long cartridge type, such as the built-in cabinet light shown in FIG. 1A and FIG. 1B. That is, the driving power, control circuit and the light unit are integrated in the case of the long cartridge. The model shown in FIG. 1A only has the alternative current (AC) power input port, and the model shown in FIG. 1A can be used individually, thus it cannot be serially connected for extending the lighting range. The model shown in FIG. 1B has both of the power input port and the power output port, thus it has expandability, in which one or more connection units can be utilized to connect with multiple light devices in series to extend the lighting range. This type of the built-in cabinet light occupies large space due to the built-in driving power and the control circuit, thus the appearance of this type of the built-in cabinet light looks bulky, thereby the transportation costs is increased and it does not meet the stylish slim design. Further, the built-in cabinet light is a design of parallel circuit when the built-in cabinet light is serially connected to be extended, in which the AC power with high voltage transmits from the output port of the first light module to the input port of the second light module through the connection unit, wherein leakage of electricity is possible during transmitting the high voltage AC power between the light modules, and the potential risk of electric shock could not be avoided when the user manipulates the light device. Further, each of the connected light devices has built-in driving circuit and control circuit in itself, thus it expenses multiple manufacturing costs and it is uneconomical. In order to improve multiple disadvantages of the commercially available products, the present invention discloses a novel design which utilizes module concept and transmitting low voltage DC power from one power module and one control module to a plurality of light modules connected in series through one or more connection units, and the serial connected light modules can be controlled by the control module alone. Wherein the control module is not necessary connected right after the power module but anywhere in the middle of light modules or even at the end through a connection unit. Aesthetics, security, expandability, control flexibility and economic low cost can be achieved such that a better cabinet lighting solution is obtained.

The power module 12 could receive an alternative current (AC) power (such as the electricity mains). The power module 12 coupled to an AC power source could utilizes internal AC/DC conversion circuit to convert the AC power to a DC power, and provides the DC power to the control module 11. However, in another embodiment, the power module 12 may not connect to the AC power source but utilize an internal DC power source or a battery to provide a DC power. When the control module 11 receives the power from the power module 12, the control module 11 could provide a control signal to the light source 10 according to the user's manipulation, for controlling the light status of the light source 10. Connection wires are utilized to establish detachable connections between each module. The user or the person of installing the light systems could conveniently achieve the installation for the light systems according to the environment, wherein the length of the connection wires for connecting each of the modules may be designed in a variety of length, for providing a flexible installation scheme corresponding to the distances between the modules and the relative positions.

The control module 11 may comprises a variety of human machine interfaces such a touch control switch, a button switch or a touchless switch (which may be an infrared sensor switch), for the user to manipulate the light system. Due to the modularized design, the control module 11 may be set up at a position anywhere within the system and after the power module allowing the user to manipulate conveniently, and also the position of the light source 10 is not influenced.

The light source 10 may comprises at least a light module or a plurality of light modules independent to each other, and the light modules could be detachably connected or removable. As shown in FIG. 2A for example, the light source 10 comprises a first light module, a second light module . . . etc. The present disclosure does not restrict the number of the light modules.

The first output portion 1012 of the first light module 101 would only be used when the user needs to connect the second light module 102 after to the first light module 101 in series. When the first light module 101 is not connected to the second light module 102, the second power terminal 1012a and the second control terminal 1012b are opened without any function. The manner of the second light module 102 connecting to the first light module 101 would be further described in the subsequent embodiment shown in FIG. 5. In a simple way, the first light module 101 can be controlled by the control module through the first input portion 1011, and the first light module 101 can transmit the electrical power and the control signal from the control module 11 to the subsequent light modules.

The first light module 101 receives the control signal through the first control terminal 1011b of the first input portion 1011, and receives the DC power through the first power terminal 1011a of the first input portion 1011. The first light module 1011 emits light according to the control signal.

The control module 11 comprises a human machine interface (HMI) (which is not shown in FIG. 4 and would be described later referring to FIG. 6), an output portion 112 and an input portion 113. The output portion 112 has a power output terminal 112a and an output control terminal 112b. The human machine interface generates the control signal and outputs the control signal through the output control terminal 112b. The first connection unit 13 has a pair of first power wires 131 and at least a first control wire 132. The output portion 112 of the control module 11 detachably connects to the first input portion 1011 of the first light module 101 through the first connection unit 13, wherein the pair of power wires 131 is used for detachably connecting to the first power terminal 1011a of the first input portion 1011 and the power output terminal 112a of the output portion 112 The first control wire 132 is for detachably connecting to the first control terminal 1011b of the first input portion 1011 and the output control terminal 112b of the output portion 112. The first power terminal 1011a of the first input portion 1011 of the first light module 101 receives the DC power from the control module 11 through the pair of first power wires 131 of the first connection unit 13. The first control terminal 1011b of the first input portion 1011 of the first light module 101 receives the control signal from the control module 11 through the first control wire 132 of the first connection unit 13. The power module 12 has a power output portion (which is not shown in FIG. 4 and would be further described thereafter referring to FIG. 7), and the power output portion detachably connects to the input portion 113 of the control module 11 through the power line 19, for providing the DC power to the control module 11.

Please refer to FIG. 3 in conjunction with FIG. 5, FIG. 5 shows a schematic diagram of a first light module of a modularized light system connecting to a second light module according to an embodiment of the instant disclosure. The circuit topology of the first light module 101 is substantially identical to the circuit topology of the second light module 102; however the present disclosure does not restrict the appearance and the size of the first light module 101 and the second light module 102. That is, the appearance and the size of the first light module 101 and the second light module 102 may not the same, but the circuit topologies of the first light module 101 and the second light module 102 are the same, having the input portions and the output portions in the same specification, wherein the input portion receives the DC power and the control signal, the output portion is for outputting the DC power and the control signal received by the light module itself (through the input portion of itself) to other subsequent connected light module. Further, the same specification of input portions and the output portions are designed for the light modules, the control module and the power module to be in compliance with the connection unit such that to provide high flexibility of module connection. For instance, a direct connection of the power module to the first light module may enable a direct driving of the light module without through the control module. Furthermore, the control module can also be connected after a light module. Such a variation of module connection is in the scope of the modularized concept of the present disclosure. The control module is in fact an optional item which can be voided by using a wall switch to operate the on/off performance of the modularized light system. Alternatively the control module can be integrated with the power module or can be integrated with the light module to become a two-module light system.

Specifically, when the first light module 101 is further connected to the second light module 102, the connection manner is described as follows. The second light module 102 has a second input portion 1021 and a second output portion 1022. The second input portion 1021 has a third power terminal 1021a and a third control terminal 1021b.

The second control wire 142 detachably connects to the second control terminal 1012b of the first output portion 1012 and the third control terminal 1021b of the second input portion 1021.

Please refer to FIG. 3 in conjunction with FIG. 5 again. When the second light module 102 is further connected to the third light module 103, the second light module 102 could utilize a third connection unit 15 for detachably connecting to the third light module 103. It is worth mentioning that the specifications of the connection terminals of the first connection unit 13, the second connection unit 14 and the third connection unit 15 are the same, however the lengths of the mentioned first connection unit 13, the second connection unit 14 and the third connection unit 15 may be different, thus the user could select the proper connection unit according requirement in practical applications, for connecting the needed number of the light modules, and the position of each light module would not be limited due to any specific length of the connection unit, the flexibility for arrangement with the use of space could be ensured accordingly.

For example, the third light module 103 has a third input portion (which is the same as the second input portion 1021) and a third output portion (which is the same as the second output portion 1022). The third input portion has a fifth power terminal (which is the same as the third power terminal 1021a) and a fifth control terminal (which is the same as the third control terminal 1021b). The third output portion has a sixth power terminal (which is the same as the fourth power terminal 1022a) and a sixth control terminal (which is the same as the fourth control terminal 1022b), wherein the third light module 103 receives the control signal through the fifth control terminal of the third input portion and receives the DC power through the fifth power terminal of the third input portion, and the third light module 103 emits light according to the control signal. The third connection unit 15 (as shown in FIG. 5) has a pair of third power wires 151 and a third control wire 152. The second output portion 1022 of the second light module 102 detachably connects to the third input terminal of the third light module 103 through the third connection unit 15, wherein the pair of third power wires 151 is for detachably connecting to the fourth power terminal 1022a of the second output portion 1022 and the fifth power terminal of the third input portion, and the third control wire 152 detachably connects to the fourth control terminal 1022b of the second output portion 1022 and the fifth control terminal of the third input portion.

Please refer to FIG. 3 in conjunction with FIG. 6, FIG. 6 shows a schematic diagram of a control module according to an embodiment of the present disclosure. The control module 11 may comprise a body 110, a human machine interface 111, an output portion 112 and an input portion 113 disposed on the body 110. The appearance of the body is for ease of explanation, but not for restricting the scope of the instant disclosure. The human machine interface of the control module may be a touch control switch, a button switch or a touchless switch (such as an infrared sensing switch), but the present disclosure is not so restricted. The type of the human machine interface 111 may be changed according to the practical requirement. And, the position of the human machine interface 111 on the body 110 is also not so restricted. The input portion 113 receives the DC power from the power module 12. The output portion 112 may has three connectors for example, in which two connectors represent the power output terminal 112a and the left one is the output control terminal 112b. The power output terminal 112a provides the DC power to the connected light module, for example the first light module 101. The first light module 101 may further transmits the DC power to the connected second light module 102, the second light module 102 may further transmits the DC power to the connected third light module 103, and so on. The connections between each light module are achieved by utilizing the connection unit, and the length of the connection unit is not limited. It is worth mentioning that the control module 11 and the light modules are positioned detachably, thus the position of the light source 10 (including all light modules) may be different from the position of the human machine interface 111 of the control module 11, for example the human machine interface 111 may be far away from the light source 10 (including all light modules). Thus, the user may not stay close to the light source 10 (including all light modules) while manipulating the human machine interface 111. The control module 11 could be arranged close any position which is convenient to the user in manipulation, and the control module 11 does not need to be at the same position of the light source 10 (including all light modules), thereby the convenience of the usage of the light system is provided.

Furthermore, the control module 11 does not need to be right after a power module. It can be positioned anywhere among the light modules or at the end of the system. The multiple control modules with the same or different human machine interfaces may be connected in the system. These provide great convenience of manipulating the system performance.

Please refer to FIG. 3 in conjunction with FIG. 4 and FIG. 7, FIG. 7 shows a schematic diagram of a power module according to an embodiment of the instant disclosure. The power module 12 comprise a body 120, an alternative current (AC) input portion 121, a battery containing portion 122, an AC/DC conversion unit 123 and three pre-punched holes 133 located in different facets of the body 120. The battery containing portion 122 could be disposed in the body 120, for installing at least one battery. The mentioned battery is for providing the direct current power, and the present disclosure does not restrict the type of the battery. The AC/DC conversion unit 123 converts the alternative current power to the direct current power. The power module 12 shown in FIG. 3 utilizes a power plug to receive the AC power. The AC/DC conversion unit 123 of the power module 12 in FIG. 7 receives the exterior AC power through the alternative current power input portion 121 of the body 120. In other words, the power module 12 may be designed as to provide the DC power by itself, such as utilizing the internal battery, or the power module 12 may convert the exterior high voltage AC power to the low voltage DC power for providing the needed DC power. The power module 12 provides a power output portion wherein the internal battery or the AC/DC conversion unit 123 utilizes the power line 19 (referring to FIG. 3 and FIG. 4) to detachably connect the input portion 113 of the control module 11 (shown in FIG. 4). It is worth mentioning that the appearance of the power module 12 is a thin box, which is especially adapted for installation of the cabinet light platform; thereby the whole light device could be inserted into a narrow flat space of the cabinet. However, the aforementioned embodiment is only for ease of explanation, the present disclosure is not so restricted. Referring to FIG. 7, the power module 12 of this embodiment connects to the AC power through the alternative current input portion 121 and transmits DC power to the control module 11 through the power output portion pertaining to the AC/DC conversion circuit 123, wherein this arrangement achieves the function of isolating high voltage AC power and low voltage DC power, so as to ensure the safety of the user. Basically, the power module 12 and the control module 11 can be designed to be separate, it only needs to use the power line 19 to connect the power module 12 and the control module 11, and the power line connected to the power module 12 and the control module 11 may be detachable, such that it is convenient for the user to change the relative positions of the power module 12 and the control module 11 base on needs, so as to increase the flexibility in the use of the light system. Besides the AC power input portion 121 of the body 120, the body 120 of the power module 12 is further designed with three pre-punched holes 133 (which are knock-out designed) located at different sides of the body, any of the pre-punched holes can be knocked to be opened for directly hard wiring the AC power lines with metal hose protection into the power module 12.

A cabinet system, particularly for kitchen cabinet, is often installed in a right angle corner in a kitchen area with two cabinet units integrated at the junction of two adjacent walls angled at 90 degrees. At the junction location where two cabinet units are integrated together a “L” shaped connector is often used to bridge the power transmission (signal transmission may also be needed for synchronization purpose) between the two adjacent under cabinet lights angled at 90 degrees with each other. In the absent of such “L” connector the connection between the two adjacent light modules often looks disordered. Furthermore, the junction location is often a dark area due to lack of an illumination unit suitable for installation at the junction location. Referring to FIG. 8 in conjunction with FIG. 9 and FIG. 10's, which schematically illustrates another embodiment of the present disclosure; wherein an under cabinet light system is installed with a kitchen cabinet system. The under cabinet light system includes three light modules 102, 103 and 104 linked together, the third light module 104 is installed with the left cabinet unit angled at 90 degrees against the other cabinet unit where the other two light modules are installed. As shown in FIG. 8, a linkable light module 200 is introduced at the junction location to bridge the light module 103 and the light module 104. The linkable light module 200 serves three functions: the first function is to be used as an organizer to make the connection at the junction look organized; the second function is to be used as a turning connector to bridge the power transmission from the third light module 103 to the fourth light module 104, wherein the two light modules are angled at 90 degrees against each other; the third function is to provide illumination to brighten the junction location. The linkable light module 200 is designed with one input portion 2011 and one output portion 2012 (see FIG. 9 and FIG. 10A), wherein the orientation of the input portion 2011 and the orientation of the output portion 2012 are angled at 90 degrees with each other; the input portion accordingly includes a power input terminal 2011a for receiving power supply and optionally may also include a control input terminal 2011b for managing synchronization, the output portion accordingly includes a power output terminal 2012a for delivering power to the next light module and may optionally include an output control terminal 2012b for delivering control signal(s) to the next connecting light module. Further refer to FIG. 10B and FIG. 10C, the linkable light module 200 is also composed of a body 3000, a light diffuser 4000 and a plurality of light-emitting diodes 5000 surface-mounted behind the light diffuser for performing illumination function. Also please refer to FIG. 10C, the linkable light module 200 comprises more than two input and output portions. Refer to FIG. 10D, the linkable module 200 is a round shape body, wherein the angle between input and output orientations is different from a 90 degrees angle.

According to above descriptions, a modularized light system and a control module and a power module thereof utilizes modularized connection manner to provide a plurality of combinations of light system, in order to meet the requirement of diverse lighting needs. Advantages of the embodiments are listed in the following: (1) A wire installation with more safety is provided. In security, the commercially available hardwire with higher voltage (such as 110V or 220V) is usually cooperated with a protection hose (applied for the European standards or American standard for example). In the modularized light system of the present disclosure, only the power module needs to connect with the hardwires, other modules such as the control module and the light module do not need to connect with the hardwires, thus applied voltage on the wiring of the control module, the light module and the connection units is lower voltage. Additionally, due to the lower voltage wires, the user does not need to worry about the leakage of electricity (in which the voltage of the leakage voltage is relative lower) when the user use the hand to touch (the switch) for manipulation. (2) A single power and a single control module are utilized to control one or more light modules, thus not all of the light modules (which may be the cabinet lights for example) have to connect with the corresponding power and control circuit in appearance. (3) The connections between the light modules are simple and can be adjusted as needed. (4) The light system could use the space efficiently, the number and the length of the wires can be reduced, thus the wire entanglement can be avoided while extending the system, and thereby the design and construction of the light system simplified. (5) The costs can be saved, and only one control module is needed even if multiple light modules are serially connected, for example: a multiple serially connected cabinet light shares the same control module. (6) The housing shapes for the three modules can be design coordinated to make the whole connected lighting system look elegantly organized in addition to the functional advantages.

The descriptions illustrated supra set forth simply the preferred embodiments of the present disclosure; however, the characteristics of the present disclosure are by no means restricted thereto. All changes, alternations, or modifications conveniently considered by those skilled in the art are deemed to be encompassed within the scope of the present disclosure delineated by the following claims.
